Clamps, Harbor Freight, auto parts stores, hardware stores, super markets and even the Dollat Stores. If I see them I pick some up. When I go to the stores with my wife I put my brain into RC mode and look at things in a different way then most people. Weights, I used to hand load my shot shells so I have hundreds of pounds of lead shot that I put into plastic bags, I too double the bags, nothing like little lead shot all ove the floor but it happens. GUess I do have a lot of clamps in the shop plus a lot of rubber bands and T-pins. I even save the pins from new shirts.
